gulp-sass no longer has a default Sass compiler

Question

I'm trying to install a foundation email project with Sass. So I follow the steps, and when I want to launch the build process by running npm start, I got this error : gulp-sass no longer has a default Sass compiler; please set one yourself.

Here is the code of my gulpfile.babel.js file :

import gulp     from 'gulp';
import plugins  from 'gulp-load-plugins';
import browser  from 'browser-sync';
import rimraf   from 'rimraf';
import panini   from 'panini';
import yargs    from 'yargs';
import lazypipe from 'lazypipe';
import inky     from 'inky';
import fs       from 'fs';
import siphon   from 'siphon-media-query';
import path     from 'path';
import merge    from 'merge-stream';
import beep     from 'beepbeep';
import colors   from 'colors';
import dartSass from 'sass';
import gulpSass from 'gulp-sass';
const sass = require('gulp-sass')(require('sass'));


const $ = plugins();

// Look for the --production flag
const PRODUCTION = !!(yargs.argv.production);
const EMAIL = yargs.argv.to;

// Declar var so that both AWS and Litmus task can use it.
var CONFIG;

// Build the "dist" folder by running all of the below tasks
gulp.task('build',
  gulp.series(clean, pages, compile, images, inline));

// Build emails, run the server, and watch for file changes
gulp.task('default',
  gulp.series('build', server, watch));

// Build emails, then send to litmus
gulp.task('litmus',
  gulp.series('build', creds, aws, litmus));

// Build emails, then send to EMAIL
gulp.task('mail',
  gulp.series('build', creds, aws, mail));

// Build emails, then zip
gulp.task('zip',
  gulp.series('build', zip));

// Delete the "dist" folder
// This happens every time a build starts
function clean(done) {
  rimraf('dist', done);
}

// Compile layouts, pages, and partials into flat HTML files

function resetPages(done) {
  panini.refresh();
  done();
}

// Copy and compress images
function images() {

    .pipe(gulp.dest('dist'));
}

// Start a server with LiveReload to preview the site in
function server(done) {
  browser.init({
    server: 'dist'
  });
  done();
}

// Watch for file changes
function watch() {

  gulp.watch(['src/layouts/**/*', 'src/partials/**/*']).on('all', gulp.series(resetPages, pages, inline, browser.reload));

}

// Inlines CSS into HTML, adds media query CSS into the `)
    .pipe($.replace, '', '')
    .pipe($.htmlmin, {
      collapseWhitespace: true,
      minifyCSS: true
    });

  return pipe();
}

// Ensure creds for Litmus are at least there.
function creds(done) {
  var configPath = './config.json';
  try { CONFIG = JSON.parse(fs.readFileSync(configPath)); }
  catch(e) {
    beep();
    console.log('[AWS]'.bold.red + ' Sorry, there was an issue locating your config.json. Please see README.md');
    process.exit();
  }
  done();
}

// Post images to AWS S3 so they are accessible to Litmus and manual test
function aws() {
  var publisher = !!CONFIG.aws ? $.awspublish.create(CONFIG.aws) : $.awspublish.create();
  var headers = {
    'Cache-Control': 'max-age=315360000, no-transform, public'
  };

  return gulp.src('./dist/assets/img/*')
    // publisher will add Content-Length, Content-Type and headers specified above
    // If not specified it will set x-amz-acl to public-read by default
    .pipe(publisher.publish(headers))

    // create a cache file to speed up consecutive uploads
    //.pipe(publisher.cache())

    // print upload updates to console
    .pipe($.awspublish.reporter());
}

// Send email to Litmus for testing. If no AWS creds then do not replace img urls.
function litmus() {
  var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;

  return gulp.src('dist/**/*.html')
    .pipe($.if(!!awsURL, $.replace(/=('|")(\/?assets\/img)/g, "=$1"+ awsURL)))
    .pipe($.litmus(CONFIG.litmus))
    .pipe(gulp.dest('dist'));
}

// Send email to specified email for testing. If no AWS creds then do not replace img urls.
function mail() {
  var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;

  if (EMAIL) {
    CONFIG.mail.to = [EMAIL];
  }

  return gulp.src('dist/**/*.html')
    .pipe($.if(!!awsURL, $.replace(/=('|")(\/?assets\/img)/g, "=$1"+ awsURL)))
    .pipe($.mail(CONFIG.mail))
    .pipe(gulp.dest('dist'));
}

// Copy and compress into Zip
function zip() {
  var dist = 'dist';
  var ext = '.html';

  function getHtmlFiles(dir) {
    return fs.readdirSync(dir)
      .filter(function(file) {
        var fileExt = path.join(dir, file);
        var isHtml = path.extname(fileExt) == ext;
        return fs.statSync(fileExt).isFile() && isHtml;
      });
  }

  var htmlFiles = getHtmlFiles(dist);

  var moveTasks = htmlFiles.map(function(file){
    var sourcePath = path.join(dist, file);
    var fileName = path.basename(sourcePath, ext);

    var moveHTML = gulp.src(sourcePath)
      .pipe($.rename(function (path) {
        path.dirname = fileName;
        return path;
      }));

    var moveImages = gulp.src(sourcePath)
      .pipe($.htmlSrc({ selector: 'img'}))
      .pipe($.rename(function (currentpath) {
        currentpath.dirname = path.join(fileName, currentpath.dirname.replace('dist', ''));
        return currentpath;
      }));

    return merge(moveHTML, moveImages)
      .pipe($.zip(fileName+ '.zip'))
      .pipe(gulp.dest('dist'));
  });

  return merge(moveTasks);
}

I've tried everything and still got the error. I'm a beginner, I'm very confused with node.js. I could downgrade my node or gulp version but I want to understand. Did I miss something ?

Thanks for your help
